Wow, lot of bad info being spouted by people who have no experience with this device. ILGal does a nice job of pointing out the benefits of the note over conventional tablets, and I thought I would reiterate and add a few things.
I got one of these when they came out so that I could organize my notes at work and it does that wonderfully. I can write on it nearly the same as a pad of paper but with the advantage of being able to organize my notes in folders for later access. I have seen iPads come into the office in an attempt to do the same thing and they disappear after a couple of weeks. The s-pen is the difference maker on this tablet. It has something like 10X the detection resolution of a typical capacitative touch screen and with 1024 levels of pressure sensitivity, the writing looks normal. It also senses the s-pen when it is above the screen, which allows for mouse over functionality, try that on any other tablet.
The resolution issue is overblown. If you hold this at about 12" or so away the human eye is incapable of resolving individual pixels. It is about angular resolution and not pixel density, which is why 1080 is fine on a 55" TV when you are 10 feet away. And let's not forget that higher resolution requires more processor capacity, larger files, and uses more battery, all for an increase in resolution that will be undetectable for nearly all people in most situations.
The plastic feel is overblown. It doesn't flex, it makes it lighter, and how many iPads are not in cases anyway?
To the person that said it will lock up, uh no. I leave mine running for weeks, never turn it off really, and haven't had it lock up even once in the several months I have owned it.
Bottom line is that the s-pen makes this a tablet that you can use for more than watching videos and surfing the web, which is what I needed in order to justify buying one. For my purposes, there isn't a better tablet available. I can sit in a meeting, take notes, get caught up on my work email, even access work files on company drives through the Citrix app, and actually be productive.
